Notes

The National Congregations Study (NCS) dataset "fills a void in the sociological study of congregations by providing, for the first time, data that can be used to draw a nationally aggregate picture of congregations" (Chaves et al. 1999, p.460). Thanks to innovations in sampling techniques, the NCS data is the first nationally representative sample of American congregations. In 2006-07, a panel component was added to the NCS. In addition to the new cross-section of congregations generated in conjunction with the 2006 General Social Survey (GSS), a stratified random sample was drawn from congregations who participated in the 1998 NCS. The 2006-07 NCS sample, then, includes a subset of cases that were also interviewed in 1998. The 2012 NCS includes an oversample of Hispanic congregations.
